Such measurements also provide reference standards, with applications in many subfields (e.g. testing theories that indicate time dependence of the fundamental constants). Determination of the behaviour of simple molecules such as oxygen and nitrogen is important for understanding the complex processes that shape the atmosphere of the earth and other planets. These experiments will also enable the understanding of other chemical processes, and will build on our strengths in developing precision laser technologies.Read moreRead less
Non-Gaussian states and entanglement distillation for Continuous Variable quantum information protocols. Amplifiers are important devices for electronic, computer as well as telecommunication industries. In the quantum world where light's corpuscular nature is prominent, amplification of a beam of light will have its associated noise penalty. This noise penalty sets limit to many quantum optical applications. This proposal aims to use a method based on conditional detection to realize a 'noisel ....Non-Gaussian states and entanglement distillation for Continuous Variable quantum information protocols. Amplifiers are important devices for electronic, computer as well as telecommunication industries. In the quantum world where light's corpuscular nature is prominent, amplification of a beam of light will have its associated noise penalty. This noise penalty sets limit to many quantum optical applications. This proposal aims to use a method based on conditional detection to realize a 'noiseless linear amplifier' that has no noise penalty probabilistically. Realization of this key device is central to extending the range of quantum communication, such as quantum cryptography. It also has applications in quantum computing and the potential to enhance sensitive measurements.Read moreRead less

The Standard Quantum Limit and Beyond. The uncertainty principle sets limits on the sensitivity to which any measurement can be made - the standard quantum limit (SQL). This limit is yet to be reached on a macroscopic object and, until recently, was regarded as unsurpassable. Due to the rapid improvement in optical measurement technology developed for Gravitational Wave Astronomy, there is now the prospect of experimentally reaching the standard quantum limit within this decade.

This limit is yet to be reached on a macroscopic object and, until recently, was regarded as unsurpassable. Due to the rapid improvement in optical measurement technology developed for Gravitational Wave Astronomy, there is now the prospect of experimentally reaching the standard quantum limit within this decade. This project will harness much of this technology to achieve the SQL. It will also experimentally develop new quantum measurement techniques to surpass this limit.Read moreRead less
